These gears com- Fla 6 1s a fragmentary, seetlonel new through prise a first gear 22, keyed to stem l2 and in mesh the disc, taken on line VI-VI of Fig. 2, and, with a second gear 24, loosely mounted upon a '5'5 Fig. 7 is a wiring diagram` illustrating the shaft 26. This second gear carries a pawl 28 55 that is yieldably pressed against ratchet by spring 32. It is through this ratchet and pawl that second gear 24 is caused to rotate shaft 26 during the actual operation of the relay, but is precluded from rotating shaft 26 While spring I6 is being wound. In other words, when spring I6 is being wound around stem I2, second gear 24 rotates freely upon shaft 26, but when gear 22 exerts force to rotate second gear 24 in` the opposite direction, pawl 28 will be effective in transmitting that force to shaft 26.

A third gear 34 is keyed to shaft 26 and is in mesh with pinion 36, which in turn is keyed to shaft I4. Ari escapement gear 38, carried by shaft 26, co-operates with the escapement yoke I6 is serving to motivate the same, Yoke 40 has a depending stem 44 that is in screw-threaded engagement with weight or pendulum 42 so that the length of the stroke might be varied to suit conditions.

Third geai' 34 is provided with a laterally extending ear 46 which engages dog 48, pivotally mounted upon pintle 50. This pintle and dog is supported by a, bracket 52 that extends upwardly from the bottom of housing 8, and said bracket is formed to present a pair of stops 54 and 56 respectively.

An electro-magnet 58 is disposed within housing 8 and actuates pivotally mounted armature 60 when energized. This armature 60 is associated with dog 48 so that it will swing the same around its pivotal support under certain conditions. Shaft 26 extends transversely across housing 8 and supports the circuit making and breaking disc 62, which has notches 64 provided therein for the reception of the curved end 66 of contact finger 68. As will be later mentioned, when contact finger 68 enters any one of the several notches 64 formed in the periphery of disc 62, contact point 10 will leave contact point 12 carried by a companion finger 14, and thereby break a circuit. Fingers 68 and 14 are resilient and mounted upon partial partition I0 in substantially the same plane as the major plane of disc 62.

Another set of contact strips` 16 and 18, having contact points 80 and 82, are mounted upon some part of housing 8 and insulated therefrom by a suitable block 84. An elevated cam face 86 projects from the side of disc 62 and engages strip 18 once during a complete revolution of disc 62. When the said strip is so engaged, points 80 and 82 are moved together to close a circuit.

It is conceivable that other means may be built into the aforesaid relay which would cause it to perform the same function `as the one just described. Such a relay is interposed in a circuit with the dialing instrument 88 of an automatic telephone system. Wires 80 and 82 join the instrument 88 with an annunciator, not here illustrated, and a supplementary circuit, having means therein for closing the same when an act to be detected is performed, also is contemplated when making a complete installation.

In the instance illustrated, switch points 84 and 86 are held open by a fusable link 88, which will release upon being subjected to a high temperature, such as when a fire occurs. This `action will, of course, close `points 84 and 86, but if a burglar alarm is to form a part of the indieating system, the means for closing switch points 84 and 86 may be mechanical ones, operated upon manual manipulation of a window, door, or the like.

Referring to Eig. 7, it will be obvious that wires 90 and 82 are joined to the above described parts of the relay and one of the circuits, including the points 94 and 96 that are closed by releasable member 88, serves as the switch or analogous device which is actuated when an act to be detected is performed. When this switch or contact points 94 and 96 are closed, electro-magnet 58 will be energized to release the mechanical parts of the relay by attracting armature 60. When armature 60 is attracted, it will be drawn against electro-magnet 58, Will swing dog 48 about pintle 50, and Withdraw the dog from engagement with ear 46. When such action occurs, spring I6 may exert its force to rotate disc 62 about its axis of rotation of shaft 26.

The circuit which is closed by the bringing together of points 84 and 86 may be traced as follows: wire 82, wire |00, wire |02, wire |04, electro-magnet 58, wire |06, contact points 82 and 80 of strips 18 and 16 respectively, wire |08, and wire IIO to line Wire 80. A

Manifestly, in the direction of the arrows circuit just traced, and thereby de-energize electro-magnet 58; such de-energization will permit the Weighte are a part, will be made and broken to transmit impulses indicating a call and a location, all in accordance with the number of When the end 66 of finger 68 drops below the normal annular plane of disc 62, the circuit is opened, and it is this mechanical act that causes the annunciator to function. The circuit which is opened and closed by the bringing together of contact points 10 and points 84 and 86, wire |02, wire |I2, contact iinger 68, closed points 10 and 12, contact finger 14, wire II4, and Wire ||0 to line 80.

When disc 62 has made one complete revolution, ear 46 will again engage dog 48 at precisely 86. signal will be repeated so long as contact points 84 and 96 remain together.

As has been mentioned before, Wires 90 and 92 may lead directly to an Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
